    Subject[PATCH 10/38] perf kvm: Update the 'record' man page entry for new --guest/--host behavior
    Date
    From: Dongsheng Yang <yangds.fnst@cn.fujitsu.com>

    As we have changed the default behavior of 'perf kvm' to --guest
    enabled, the parts of the man page that covers the 'record' subcommand
    are outdated.

    This patch updates it to show the correct output with
    --host/--guest/neither/both of them.
